Dianthus plant named ‘WP09 MAR05’

ABSTRACT

A new cultivar of  Dianthus  plant named ‘WP09 MAR05’ which is characterized by compact plant habit and early blooming fully double crimson colored flowers. In combination, these characteristics set ‘WP09 MAR05’ apart from all other existing varieties of  Dianthus  known to the inventor.

Genus: Dianthus.

Species: ×hybrida.

Denomination: ‘WP09 MAR05’.

BACKGROUND OF THE INVENTION

This application claims the benefit of priority under 35 U.S.C. 119(f)of the application for a grant of European Community Plant BreedersRights which was filed for the instant plant variety on Mar. 9, 2009,Application Number 2009/0421.

The present invention relates to a new and distinct cultivar of hardygarden pink or carnation that is grown for use as a flowering plant forpots and containers and for planting in the garden and landscape. Thenew cultivar is known botanically as Dianthus×hybrida and will bereferred to hereinafter by the cultivar name ‘WP09 MAR05’.

‘WP09 MAR05’ is a complex hybrid plant that is the product of a breedingprogram started by the inventor in 1985. The breeding program isconducted in a cultivated area of Houndspool, Dawlish, Devon, UnitedKingdom. The inventor selected ‘WP09 MAR05’ in 2005 for its early seasonflowering and for its fully double crimson flowers which are fragrantand produced in profusion.

‘WP09 MAR05’ resulted from the controlled pollination between twounreleased and unpatented selections of Dianthus from the inventor'sbreeding program, namely Selection “98.02” as male parent and Selection“ASH22” as female parent.

‘WP09 MAR05’ is distinguishable from the male parent as follows: Theheight of the male parent is approximately two times the height of ‘WP09MAR05’. The length of the flower stems of the male parent isapproximately two times the length of the flower stems of ‘WP09 MAR05’.The flowers of the male parent are pink-magenta in color whereas theflowers of ‘WP09 MAR05’ are crimson in color.

‘WP09 MAR05’ is distinguishable from the female parent as follows: Theflowers of the female parent are semi-double in form and are carmine incolor, whereas the flowers of ‘WP09 MAR05’ are fully double and arecrimson in color.

The variety of Dianthus which is considered by the inventor to mostclosely resemble ‘WP09 MAR05’ is Dianthus ‘WP PASSION’ (U.S. Plantpatent Pending, application Ser. No. 12/220,573, filed Jul. 24, 2008.)‘WP09 MAR05’ is distinguishable from this variety by plant height.Whereas plants of ‘WP PASSION’ are approximately 30 cm-35 cm in heightafter 9 months of growth, plants of ‘WP09 MAR05’ are 10 cm-13 cm inheight after nine months of growth.

Asexual reproduction of ‘WP09 MAR05’ was first accomplished by theinventor in 2005 in a cultivated area of Houndspool, United Kingdom. Themethod of asexual propagation used was vegetative cuttings. Since thattime the characteristics of the new cultivar have been determined stableand are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent thecharacteristics of the new Dianthus cultivar ‘WP09 MAR05’. These traitsin combination distinguish this cultivar from all other commercialvarieties known to the inventor. ‘WP09 MAR05’ has not been tested underall possible conditions and phenotypic differences may be observed withvariations in environmental, climatic and cultural conditions, however,without any variance in genotype.

Dianthus ‘WP09 MAR05’ is perennial and is hardy to −15° C.    -   8. Dianthus ‘WP09 MAR05’ is suitable for use as a flowering        plant in pots and containers.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of thenew Dianthus variety ‘WP09 MAR05’ showing colors as true as it isreasonably possible to obtain in colored reproductions of this type.Colors in the drawings may differ from the color values cited in thedetailed botanical description, which accurately describe the actualcolors of the new variety ‘WP09 MAR05’.

The drawing labeled as FIG. 1 depicts an entire flowering plant.

The drawing labeled as FIG. 2 depicts a close-up view of the flower.

All drawings were made of 9 months old plants which have been grown in1.5-liter containers in a cold glasshouse in Devon, United Kingdom. Nochemicals were used to treat the plants. All drawings were made usingconventional techniques and although colors may appear different fromactual colors due to light reflectance they are as accurate as possibleby conventional photography.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new cultivar ‘WP09MAR05’. Data was collected in spring from 1.5-liter container plants inspring, and grown indoors in Devon, United Kingdom. The colordeterminations are in accordance with the 2002 edition of The RoyalHorticultural Society Colour Chart of The Royal Horticultural Society,London, England, except where general color terms of ordinary dictionarysignificance are used. The colors of stems, leaves, calyx, and epicalyxhave been noted on plants which retain the characteristic waxy bloom ofDianthus. No chemicals were used to treat the plants. Growing conditionsare typical to other Dianthus.
